Once the first booting process complete well, the system turns off automatically.It did a rootfs auto-resizing and ssh initialization within a minute.After that, you have to unplug/plug the DC plug again.

BTW, can you connect the HC2 to your PC directly without router to narrow down root causes?

When it's connected to my router, it lists the computers that have wired connections to my router. I can account for all of the IPs it lists. But it doesn't list the HC2.On my router, I can click the MAC address of each connected device and it shows me the manufacturer. None of the devices have a MAC that starts with 00:1e:06

LED behaviors look fine.Green: Flashes when there is 100Mbps connectivityYellow: Flashes when there is 1000Mbps connectivity

The possibility of both of two HC2 defectives is extremely low since our overall product failure rate is lower than 0.1%.So please try this OMV image(OMV_3_0_92_Odroidxu4_4.9.61.img.xz) only for the hardware configuration test.https://sourceforge.net/projects/openme ... %20images/Please note the OMV initialization takes a couple of minutes in the first boot process.
